Abstract

Disclosed are a concrete dowel placement devices and a method of utilizing the same. A metallic stud is driven, screwed, or otherwise attached to a form. The stud may be a unitary structure, or may be a hollow tube with conventional fastening means such as nails and screws extending through and holding the hollow tube to the form. A cover having an interior compartment substantially equal in diameter to the stud is slidably placed thereon, and a first enclosed area is developed with a plurality of forms. Concrete is poured into the first enclosed area, and upon curing, the form and the stud are removed, leaving the cover embedded in the concrete. A metallic dowel is inserted into the cover, and a second enclosed area is developed with like configured forms. The metallic dowel extends into the second enclosed area. Upon pouring concrete into the second enclosed area, a cold joint is formed between the concrete of the first enclosed area and the concrete of the second enclosed area, supported and braced by the metallic dowel.

Claims

1. A concrete dowel placement device for attachment to a form, comprising:

a stud having a generally tubular body, a proximal stud end and a distal stud end; and

a cover having a generally tubular body having an outer cover surface, an open proximal cover end that abuts against said form, a closed distal cover end, and a hollow cover interior compartment extending axially therein configured to slidably receive said stud.

2. The concrete dowel placement device as set forth in claim 1, wherein said stud is of uniform construction and has a form insertion section disposed towards said proximal stud end and encompassed by said form, and a cover insertion section disposed towards said distal stud end and encompassed by said cover, wherein said form insertion section extends beyond said proximal cover end when said cover is placed on said stud.

3. The concrete dowel placement device as set forth in claim 2, wherein said form insertion section is tapered to a point defining said proximal stud end for ease in driving said stud into said form.

4. The concrete dowel placement device as set forth in claim 2, wherein said form insertion section is threaded and tapered to a point defined by said proximal stud end for screwing said stud into said form.

5. The concrete dowel placement device as set forth in claim 4, wherein said distal stud end defines a molded surface configured to cooperate with a screwdriver head.

6. The concrete dowel placement device as set forth in claim 1, wherein said distal stud end and said proximal stud end each have an opening, and a hollow stud interior compartment extending axially therebetween.

7. The concrete dowel placement device as set forth in claim 6, wherein said stud is configured to slidably receive a nail having a length greater than that of said hollow stud interior compartment, said nail having a head in an abutting relationship with said distal stud end and a point driven into said form.

8. The concrete dowel placement device as set forth in claim 6, wherein said stud is configured to receive a threaded screw having a length greater than that of said hollow stud interior compartment, said screw having a head in an abutting relationship with said distal stud end and a point screwed into said form.

9. The concrete dowel placement device as set forth in claim 8, wherein said stud further includes threading to cooperatively retain said threaded screw.

10. The concrete dowel placement device as set forth in claim 1, wherein said cover includes an integrated flange on said proximal cover end.

11. The concrete dowel placement device as set forth in claim 1, wherein said cover is formed of plastic.

12. The concrete dowel placement device as set forth in claim 1, wherein said stud is ¼

inch in diameter.

13. A method for forming a cold joint between adjoining sequentially formed slabs of concrete, the method comprising:

forming a first enclosed area with forms having a stud attached thereto, and a first cover attached to said stud, said first cover abutting the form;

pouring a first slab of concrete into said first enclosed area;

slidably removing said forms from said first slab of concrete upon curing, in which said stud is removed from said first cover, said first cover remaining within said first slab of concrete, an end of said first cover being coterminous with said first slab of concrete;

inserting a dowel into said first cover remaining in said first slab of concrete;

forming a second enclosed area adjacent to said first slab of concrete with said forms, said first concrete slab defining at least a part of said second enclosed area, and said dowel extending into said second enclosed area; and

pouring a second slab of concrete into said second enclosed area.

14. The method as set forth in claim 13, wherein said step of forming a second enclosed area further comprises the step of:

attaching a second cover onto said stud on said form.

15. The method as set forth in claim 13, wherein said dowel is generally cylindrical.

16. The method as set forth in claim 13, wherein said dowel is constructed of stainless steel.

17. The method as set forth in claim 13, wherein said cover is molded of plastic.
